Plants make food in their leaves. The leaves contain a pigment called chlorophyll, which colors the leaves green. Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis.
The green color in leaves is caused by the presence of a compound called chlorophyll, which the plant produces to do photosynthesis, which is how plants get energy from sunlight. The purpose of chlorophyll is to assist the plant in making food for itself by utilizing energy from sunlight and nutrients from the soil.
